This paper presents a dimensionless model for the depth of penetration (DOP) of a projectile penetrating into a concrete target, based on the similarity theory involving intermediate asymptotics, complete similarity, and incomplete similarity. The calcula... see more

Semi-infinite targets of Ultra-High-Performance Fibre-Reinforced Concrete with various fibre volume fractions were subjected to the high-velocity projectile impact using in-service bullets. In this study, a variety of empirical and semi-analytical models ... see more

The main problem of this study is that students who are not able to gain the minimum score were not given remedial teaching and learning that were adjusted to their learning style. This study aimed to determine the effect, improvement, and effectiveness o... see more

Nonlinear frequency responses of the laminated carbon/epoxy composite curved shell panels have been investigated numerically and validated with in-house experimentation. The nonlinear responses have been computed numerically via customised computer code d... see more

Flow around a conical nose with rounded tail projectile has been studied numerically for subsonic, transonic and supersonic flow regimes. The conic angle of the projectile is 10°. The inflow Mach numbers are 0.5, 0.9, and 1.5. Axisymmetric Euler’s equatio... see more

Recent studies of Gurtin [8,9,10], Angenent and Gurtin [4], and Gurtin and Struthers [15] form an investigation whose goal is a nonequilibrium thermodynamics of two-phase continua in which the interface is sharp and endowed with energy, entropy and superf... see more

Ballistic impact of a steel projectile on armour steel plate is examined by numerical simulations using 3-D nonlinear dynamic explicit finite element code ANSYS LS-DYNA. Simulations are attempted using a simple strain rate dependent plasticity model that ... see more

Context. Within the framework of the accepted simplifying hypotheses, an approximate scheme of calculation of the parameters of the active and passive sections of the trajectory is proposed, which allow to study the trajectory properties of the existing a... see more

Bullet proof vests, made of Kevlar are used for preventing projectiles from injuring humans. Soft armours are capable of protecting humans from low energy projectiles while hard-plate reinforced armours use metal plates, which weigh over 14+ kg for protec... see more
